Self-editing checklist for crime, mystery and thriller writers

20/3/2026

Before you send your manuscript to an agent, editor or beta reader, use this comprehensive 10-step checklist to ensure your story is as tight, compelling and credible as possible.

Why self-editing is part of the writing process

A loose end, unconvincing motive, lack of tension and suspense, or mistimed reveal can unravel an otherwise gripping story. For that reason, self-editing is more than just a final step. Instead, think of it as a critical part of your writing craft process.

Check #1: Plot and structure: Does the mystery hold up?

Start with the backbone of your story: the plot.

Strong crime fiction and thrillers typically follow a clear trajectory – setup, investigation, escalation and resolution. That doesn’t mean the novel has to be predictable, but the reader does need to be able to see the logic in the events as they unfold.

In particular, ask yourself whether there any coincidences that solve too problems conveniently. It’s important that any key twists feel earned, rather than shoehorned in to make the story work.

Pay special attention to your ending. A satisfying resolution should feel both surprising and inevitable.

TIP: One useful technique is to work backwards from the reveal. Does every major plot point support that conclusion?

Check #2: Clues and red herrings: Are you playing fair?

Crime, mystery and thriller readers love trying to solve the puzzle alongside the protagonist. That means you need to play fair.

Every crucial clue should have been planted before the reveal. That means finding a balance between keeping those clues obscure but not completely hidden. not hidden, but not obvious either.

As for red herrings, these need to mislead without feeling manipulative or obvious. If readers feel they’ve been tricked rather than challenged, the story loses credibility.
The Golden Age writers were particularly adept at this, making sure that all the pieces are there and, ultimately, fit together.

TIP: Ask yourself whether an attentive reader could solve this mystery well before the ending?

Check #3: Character behaviour: Is it consistent and logical?

In this genre, the transgressive behaviour hinges on human behaviour – the characters’ motives, opportunities and psychology.

Consistency doesn’t require that a character can’t change. They can, and in that case that change will be key to the story’s arc. However, that change needs to make sense for the reader and driven in a way that’s clear to them.

Review each major character and check that:

their motivations are clear and believable
their actions align with their personality, especially when they’re under pressure
the suspects are distinct enough for readers to keep track of them.

TIP: Pay special attention to your antagonist. Their actions must make sense within the logic of the story. A brilliant twist won’t land well if the character behind it feels underdeveloped or inconsistent.

Check #4: Character names: Are they distinct?

Confusion is the enemy of tight crime and thriller writing. And nothing’s more confusing that when characters have the same names.

Of course, that’s something we experience in everyday life, but when it comes to novel writing, readers need to be able to identify who’s who. That becomes even more important when you’re writing a series because to ensure continuity, there’ll be no going back!

Make sure that:

each first name is distinct to avoid confusing readers, especially when there are multiple suspects (no reader will thank you if there are four Johns and five Wills/Bills)
you’ve avoided overly similar-sounding first and last names or repeating initials
the name reflects the character’s age, culture and social context
you verify spelling, titles and surnames to ensure they’ve remained the same from chapter to chapter (or even book to book in a series).

TIP: Create a simple character list or spreadsheet to track names, titles, appearances, traits and relationships.

Check #5: Timeline and continuity: Does everything add up?

Crime, mystery and thrillers often involve intricate timelines – alibis, movements, sequences of events. This is where many drafts fall apart.

Comb your draft manuscript and check the following:

Do all events occur in a logical order?
Are alibis consistent and verifiable?
Are there any contradictions in time, place or action?

TIP: Creating a separate timeline document can make this job easier. List exactly where each character is at every key moment. If something doesn’t line up there, it won’t line up for your reader either.

Check #6: Procedure: Is it plausible but engaging?

You don’t need to be a forensic expert to write in this genre, but your story does need to feel plausible, even if the setting is speculative.

Chris Brookmyre’s Places in the Darkness is a superb example. It follows a murder investigation on a near-future space station, where politics, class and human behaviour drive the mystery. Despite the speculative setting, it feels plausible because the crime – and its motives – are grounded in recognisably human conflicts.

Bear in mind that fiction can become dull if it mirrors real investigations too closely – lots of details about paperwork, delays and routine steps can drain tension and suspense.

Check the following:

Are investigative procedures plausible?
Is the forensic detail accurate within the novel’s world-build?
Is the forensic detail useful but not overwhelming?
Are legal consequences believable?

TIP: Prioritise tension over total realism. Include only the procedural details that increase the stakes, help the reader make sense of the investigation or reveal a character more deeply.

Check #7: Is the dialogue engaging and purposeful?

Dialogue is one of the most powerful tools for building tension and revealing character.

When a character’s speech focuses too much on everyday but mundane information – like discussions about the weather or how people take their coffee – readers can become bored, even though what’s being said would happen in real life.

As you edit:

cut any lines that don’t serve a purpose
ensure that each major character has a distinct and consistent voice
avoid using dialogue purely for exposition, sometimes called maid-and-butler dialogue.

TIP: Read your dialogue aloud. If it feels awkward to say, it’ll feel awkward to read.

Check #8: Pacing and suspense: Do they keep readers hooked?

Crime, mysteries and thrillers need to pull readers forward relentlessly.

Each scene should either advance the plot, deepen character or increase tension – ideally all three. If it doesn’t, consider cutting or rewriting it.

Look out for:

sections where the story drags or stalls
overlong descriptions that slow momentum
chapters that end in a way that doesn’t urge readers to turn the page.

TIP: End every chapter with a question or unresolved tension. This article has 7 suggestions that will help you do that at line level.

Check #9: Point of view: Are the shifts in perspective clear?

When readers have access to what’s going on in every character’s head in a single scene, head-hopping might be in play.

That can rip tension and suspense from your novel because readers know what everyone’s thinking and feeling. Nothing’s withheld.

More crucially, perhaps, it stops them investing in a character’s experience in the moment. The psychic distance widens and makes them feel like they’re a distant observer rather than a participant.

Of course, it’s fine to have more than one viewpoint character, but check that:

you’ve chosen a consistent viewpoint approach throughout the novel
any shifts from one character’s perspective to another’s are intentional and clearly signposted
you give your readers opportunities to feel almost like they’re in a single character’s head

TIP: Highlight every sentence in which there’s information that your POV character couldn’t directly perceive or know. If anything slips through (another character’s thoughts, unseen actions), you’ve broken viewpoint, and it’s time to revise so everything is filtered strictly through that character’s experience.

Check #10: Line craft: Is your writing sharp?

Effective line craft sharpens prose by making every sentence purposeful, precise and engaging. When we line edit, we’re seeking to enhance clarity, tone and rhythm and to eliminate excess.

That way the story flows smoothly and keeps readers immersed. Zoom in on your narrative and focus on the following:

Cutting repetition and filler.
Replacing vague descriptions with specific details.
Eliminating clichés and overused phrases.
Considering every adverb to make sure it’s not telling what’s already been shown through dialogue and action.

TIP: Trust your readers, then cut unnecessary words. If a word, phrase or sentence doesn’t reveal character, advance the plot or heighten tension, remove it.

Summing up

Robust self-editing will mean your draft is in the best shape possible before it goes to someone else. It might feel like a time-consuming thing to do, but it will save you time in the long run, and perhaps even money.
